Are Audi drivers the biggest assholes on the road?

It was always assumed that BMW drivers took the crown when it came to driving like a prick on public roads. Well, Audi owners may be challenging for the title. Take a look at this vid of an R8 dodging traffic at triple digits.

We have all done stupid things on the road but this easily could have ended badly taking out not just the R8 but people with their kids in the car. What was the guy thinking?
